Very long time ago, I believe, to install the plugin to the right places, I used www-plugins/nspluginwrapper. Just emerge it. I don't know if it is still preferred way, though.
EDIT: Check Gentoo Adobe_Flash Wiki. Notice, It mentiones netscape-flash which is now named adobe-flash. You already have it._________________Anyway it's all the same at the end...
Need help to get it working: "x-fi surround 5.1"

Even after inputting those commands, Firefox still can't play YouTube videos.

I emerged nspluginwrapper-1.2.2-r2 but Firefox still can't play YouTube videos.

Recently I had some issue with the Adobe PDF reader seemingly not working with firefox.

I ended up just installing a link in /usr/lib/mozilla-firefox/plugins --

Currently I have:

libflashplayer.so -> /opt/netscape/plugins/libflashplayer.so

and

nppdf.so -> /opt/Adobe/Reader9/Browser/intellinux/nppdf.so

for flash and acroread, respectively.

But it is weird, the plugin is showing up in tools/add-ons/plugins but about:plugins does not have it listed?_________________Intel Core i7 2700K@ 4.1GHz/HD3000 graphics/8GB DDR3/180GB SSDWhat am I supposed to be advocating?

I don't remember, (installed flash a long time ago) but do you have to do anything in the browser like "Get the latest flash plugin" which appears if you want to display flash in the browser but you haven't installed yet?
Or it doesn't make sense in linux and/or gentoo?

Linux tends to need special instructions to install, I never trusted "get latest flash plugin" buttons, more system-correct for Gentoo to grab it through portage... At best the "get latest flash" should install for just the current user.

but I fear there may be some disconnect for flashplayer/pdfreader for firefox..._________________Intel Core i7 2700K@ 4.1GHz/HD3000 graphics/8GB DDR3/180GB SSDWhat am I supposed to be advocating?

* Do so for every Adobe package you install, or plugin that refuses to play nice.

* Start firefox and go to Tools->Add-On->Plugins
The plugin should be listed and enabled.

* If this did not work, try this:
+ cd ../searchplugins
+ ln -s ../plugins/*.so . (note the period - it means "here")
If it does not help, it does no harm either.

Note: If objects files (output of ls -l) is not deterministic, check this:

* df ~
This will tell you what filesystem your home directory is actually in.

* grep </my/home/fs> /etc/fstab
This will show you how the filesystem is mounted.

* Check that the parameter noatime is not listed on this line.
If it is, either remove this word or delete the no (making the word "atime")
This will make sure the filesystem will update the date of the latest access to the
directories. Normally, this is a waste of time/resources, but it is a good way to see
when any object was accessed, not just modified.
To see access time, use ls -aul.
